well, we are getting used to transitions ;-) Last time I checked the
LSB list mentioned by Benjamin, I couldn't find any activity on the
C++ issues.
What I read from the gcc lists, I am under the impression that 3.3
doesn't change the ABI from the 3.2 series. Two ABI transitions in
three months would really hurt. My plan is to make 3.3 the default
compiler at least on some architectures, when it's released.
